` 'Be it known that I, H. E. FhnmclL-of Easton, in the county of Northampton', andIStateoPennsylmnia,

- have invented a new and useful Improvement in Sewing Machines', and I do hereby declare that the following is a, full, clear, Iand exact description thereof, which will-enable' those skilled in the art'lto make and usevthe samen reference' being had to theaccompanying drawings, forming part of this specification, in whichvFigures 1, 3, and -4 are sideviews of my invention..v V

Figures 'and''are'end views of the same Similar letters of reference indica-te corresponding parts. Y p

This invention relates to certain improvements on the button-hole sewing machine for which Letters Patent were granted to D. W. G. Humphrey on the 7th day' of October, 1862, '29th of' August, 1865,V and October 3d,

l 1865. Said improvements consist in the use ofwire arms, which are laid over the' spools for the purpose of r holding the thread, and for preventing it from slipping, said arm's bcing'secured stationary to the machine.

A, fig. 1, represents one of the two spools which are arranged on the under side of the machine, arid around which one of the threads is wound. A portion of the platform of the `sewing machine is represented by red lines. B is a wire, one end of which is secured to a'me'tal jaw, C,.whichis provided with a set-screw, D, by

which thewire is secured to the iange around the platform. The wire isA bent so as to iit over the spool, andA its free end is perforated, furthe thread to pass. through, as Is clearly shoiv'n in tig. 1. The thread, by the use of this device, is prevented from falling 0E the spool, and its tension is increased. E, figs. 2vand 3, is a similar wire, which is also secured to a jaw, C, and provided with n. set-screw, D,- and with a hole in its free end. It is Ito' ,he used for the other spool below the platform Vof the machinefor the same purpose above set forth. Avvire,

., which is similarly connected and arranged, is secured to the top of the machine, and applied to the upper third spool, also for the purpose of retaining thethread on the spool, and for increasing` the tension.

I claim as new, and desire to secure by Letters Patent, as an improved articleot` manufacture-4 The'wircs B E and F, when arranged substantially as and for the purpose herein shown and described, in

'combination with the jaws C and set-screw D, all to be applied to the button-hole sewing machine, as set forth.
